Pitch automation clip?

Is there anyone that can tell me if there's a vst that does this,
or how to do this in FL studio 9, 'cause i can't find it.
I could do it in the synthesizer but that'd take way more work than an automation clip.

Comb filters are great to create all kinds of weird harmonies in your sound.
I was working on the sounds for a video project and needed to make some robotic sounds.
Comb filters in combination with other filters work really well for that!
